SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world.
And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.
You can get more information from the ac6-tools website and download two short videos (registration required) highlighting:

System Workbench for STM32

sprintf / _sbrk make error

Dear ST support,

Using the nano.spec linker directive, compilation returns the error mentioned in the beginning of this post about _sbrk missing. This is seemingly due to the use of sprintf. Nevertheless, I am willing to use a sprintf function which requires no dynamic allocation (as we forbid this in a memory constraint application).

Is it possible to achieve this with the current provided glibc?
In addition, is it possible to have more information about the provided C library ?
Notably, could you provide the link to the repository holding the library source code (is it the classic glibc one found at https://www.gnu.org/software/libc/sources.html?)Question ?

Thanks for your help,
Best regards
Sylvain
